How to increase salinity??

[Le Dirk]

So today I tested the salinity of my water, as my corals weren’t looking too hot. It was setting around 1.020, and I thought that maybe a single water change would fix that, but it didn’t. How do I increase my salinity so my corals won’t suffer??

Just do more water changes at 1.026/1.027sg or maybe a little higher to raise it up. You can also top off with salt water to raise it up.

Turn of ato and replace evaporated water daily with regular saltwater until you reach desired salinity.

To increase salinity slowly, I top off my tank’s evaporation loss with saltwater instead of DI water.

Thank you, I tried just that and I got it slowly back up to 1.025!!

How do you know that it was really 1.020 and what do you suppose caused it to drop so low?
